| Popis: | Multislice computed tomography (MSCT) has been currently utilized as a non-invasive diagnostic modality to detect coronary artery disease. We sought to investigate whether preprocedural lesion assessment by MSCT could offer strategic guidance in the setting of elective complex percutaneous coronary intervention (PCI). Twenty-six complex coronary artery lesions in 23 patients were evaluated using 16-row MSCT scanner and an off-line image analysis workstation prior to the PCI. Procedural strategies of PCI were planned based on the morphologic and geometric analysis of the target lesion and vessel. MSCT provided valuable strategic information, which was useful for subsequent PCI procedure. The three-dimensional computed tomography (CT) images allowed us to determine optimal working view angle that best demonstrated the target lesion with least foreshortening. Furthermore, the thin-slab maximum intensity projected CT images of the target lesion served as a preprocedural road map depicting the bends of complex luminal path, vessel geometry and occluded segment of the vessel. As results, procedural success was achieved in all cases with complex lesions including chronic total occlusion. Our preliminary results showed that preprocedural lesion and vessel assessment by MSCT provided important additive strategic information that led to successful complex PCI procedures. |
